Fnd0ParticipantEligibility constant: Need to evaluate multiple group/role combos Please enhance the Fnd0ParticipantEligibility property constant. Presently it only evaluates a single group/role combination. We need support for multiple group/role combinations.
You'll need to contact GTAC to get the current status, but I've not spotted anything in the release notes so I suspect it's still open.
Is there a way to render the information in the Stylesheet for the Custom Participants in the same way it appears for the OOTB participants ie; a link displaying combination of group /role/ user ?
A dynamic Participant is defined in RAC with the option Assign Participants and will be assigned to the Object.
You should define this option in the Stylesheet of the object. You can check in the workflow if this participant is defined and if not create a DO task with instruction on how to define the participant
Some customers want to use the dynamic participant depending on the project. In that case you have to write some customizing. You define a user with a specific role in TC Project and this user will be assigned as the correct particpant to the object
